MiR-301a is activated by the Wnt/β-catenin pathway and promotes glioma cell invasion by suppressing SEPT7.

Background: miR-301a is frequently dysregulated and specific to human tumors, playing a critical role in tumorigenesis; however, the exact functions and regulatory mechanisms of miR-301a in glioma cells remain largely unknown. Herein, we show that miR-301a activated by the Wnt/β-catenin pathway promoted the invasion of glioma cells by directly targeting SEPT7.

Methods: Biochemical, luciferase reporter, and hromatin immunoprecipitation PCR assays characterized the function and regulatory mechanisms of miR-301a in glioma invasion.

Downregulation of serum microRNA-205 as a potential diagnostic and prognostic biomarker for human glioma.

OBJECT Circulating microRNAs (miRNAs) are a new class of highly promising cancer biomarkers. Malignant glioma is one of the most devastating and lethal forms of intrinsic CNS tumor. Here, the authors evaluated serum miRNA 205 (miR-205) levels in patients with glioma.

Sulforaphane enhances temozolomide-induced apoptosis because of down-regulation of miR-21 via Wnt/β-catenin signaling in glioblastoma.

Temozolomide (TMZ) has been widely used in the treatment of glioblastoma (GBM), although inherent or acquired resistance restricts the application. This study was aimed to evaluate the efficacy of sulforaphane (SFN) to TMZ-induced apoptosis in GBM cells and the potential mechanism. Biochemical assays and subcutaneous tumor establishment were used to characterize the function of SFN in TMZ-induced apoptosis.

A meta-analysis of carotid endarterectomy versus stenting in the treatment of symptomatic carotid stenosis.

Background: Carotid stenosis is one of the common reasons for patients with ischemic stroke, and the two invasive options carotid endarterectomy (CEA) and carotid artery stenting (CAS) are the most popular treatments. But the relative efficacy and safety of the methods are not clear.

Methods: About 521 articles related to CAS and CEA for carotid stenosis published in 1995 - 2011 were retrieved from MEDLINE, Cochrane Library (CL), and China National Knowledge Infrastructure (CNKI) China Journal Full-Test database.

MiR-21 modulates hTERT through a STAT3-dependent manner on glioblastoma cell growth.

Background And Purpose: As an important oncogenic miRNA, miR-21 has been reported to play crucial roles in glioblastoma (GBM) carcinogenesis. However, the precise biological function and molecular mechanism of miR-21 in GBM remain elusive. This study is designed to explore the mechanism of miR-21 involved in the control of GBM cell growth.

MicroRNA-21 expression is regulated by β-catenin/STAT3 pathway and promotes glioma cell invasion by direct targeting RECK.

Aims: MicroRNA-21 (miR-21) expression is increased in many types of human malignancy, including glioma. Recent studies report that miR-21 regulates cell invasion by targeting RECK, however, the underlying transcriptional regulation of miR-21 in glioma cells remains elusive.

Results: Here, we identify a positive correlation between miR-21 expression and pathological grade in glioma tissues.

Interruption of β-catenin suppresses the EGFR pathway by blocking multiple oncogenic targets in human glioma cells.

Malignant gliomas are the most common type of intrinsic central nervous system (CNS) tumors with high mortality and morbidity. β-catenin is overexpressed in human glioblastoma and knockdown of β-catenin inhibits glioblastoma cell proliferation and invasive ability, and induces apoptotic cell death. Furthermore, treating the nude mice carrying established subcutaneous LN229 gliomas with siRNA targeting β-catenin intratumorally also delayed the tumor growth.
